Calibration data is extracted by sampling the field of each radiator at certain locations near the array by fixed probe antennas. A scalable calibration model for evaluation of the measured data is described. First tests are performed on a small passive array representing a unit cell of larger arrays. The calibration scheme is subsequently applied to and tested on a 64 element DBF transmit antenna array.en0018-926X201015967Antenna arrayCalibrationDigital beamformingProbe antennaAllgemeines, WissenschaftJournal Article10.1109/TAP.2009.2036195Other
